PENCIL.

' Application filed February 1, 1924. Serial No. 689,870.

My invention relates to improvements in magazine pencils ofthat class inwhich a lead-- carrying member telescoplngly fits within an outercasing, the object of the lnvention being particularly to provideimproved means for removably supporting the lead on the end of the innermember, and to this end my invention consists in the construction, com-'bination, and arrangement of parts herein after described and claimed.

In the accompanying drawings:

Figure 1, represents a longitudinal central cross section of a pencilcontaining my features of invention.

Figure 2, is a perspective view of the lead holding portion of thepencil.

Figure 3, is a perspective'view of one member of the lead holding means.

Figure 4, is a section on line xw of Figure 1.

Figure 5, is a section on line y y of Figure 1.

Figure 6, represents a longitudinal central cross section of a modifiedform of my pencil.

Figure 7, is aperspective View of the lead holding means embodied in theconstruction shown in Figure 6; and

Figure 8, is a perspective View of one member of said lead holdingmeans.

Referring to the drawings, A and B repre sent respectively inner andOlltGIiGlBSCOPlIlg sections. The outer casing has a contracted end, thetip of said end being formed with an opening 3 through which the leadmaybe fed or. retracted by the sliding of theanner within the outercasing. The opposlte or inner end of the outercasing isv open to permitthe insertion or removal of the inner casing. The outer end of the inner02.5111 may be circumferentially expanded to affbrd a holder 4 for aneraser 5, the inner end of said holder portion forming a stop for theinner casing. The casing is preferably formed with aremovable inner end6. By removing the inner end 6, extra leads may be placed in the innercasing to perm1t the same serving as a holding magazine.

Frictional engagement between the inner and outer casingsmay be securedas by a slotted expansion portion 7 in the wall of the inner casing. I

For the purpose of supporting the lead or crayon 8, I provide in theform shown in Fig ure 1, the following described means. These meanscomprise a stem 9 having a head 10 held between washers 11 and 12supported inthe inner end of the inner casing section I 6. The washersare aflixedin the inner end of the inner casing by crimping in the wallof the casing to grip the washers and firmly hold them against rotation.The stem extends outwardly through an opening in the pin 13 extendingthrough a rectangular openmg in the washer 12 whereby to preventrotation of the stem. lidably supported upon washer 11 and is formedwith arectangular V the outer end of the stem is the sleeve 14, thesleeve being slidably held in position upon the stem. by means of theinturned portion 15 projecting into a-slot 16 formed in one side of thestem. The sleeve is preferably of longitudinally spit construction, asshown in Figure 2, to permit its projecting end to maintain a springgripupon the con tained lead or crayon.

In the modified constructionshown in Figure 6, the stem at one end isformed with a squared shoulder 17 extending through a lead is fed orretracted by rotating and sliding the inner casing within the outercasing.

The particular construct-ion of pencil through" which the lead isretracted or fed is not a part of the present invention, and any desiredconstruction may be applied. The present invention provides a leadholding means whereby a sl idable lead holding sleeve may be used infreeing the lead or crayon and whereinthe lead is protected in use andin ice the freeing operation by the hereinbefore described means forpreventing rotation of thestem. In removing the lead the sleeve issimply pulled back over the stem to free the lead, and in placing thelead in position the sleeve is moved outwardly beyond the stem over thelead.

The word lead is employed in this case as including ordinary; leads,crayons, or other markers.

I claim:
